Be it known that LIALBERT H. Dn Von,

a citizen of the United States, residing at VVestfield, in the county ofUnion and State of New Jersey, have invented certain new "and usefulImprovements in Attachments I It aims to provide a new and improvedcombination and arrangement of attach ments for making'an ornamentalfacing for body garments of the character shown in my prior Patent No.1,239,675,-granted September 11, 1917, on a combined ruining and Theexact-Y ornamental stitching machine. ing demands ofthe tradenecessitate precision and uniformity productionand the present inventionanswers these requirements. W

The invention comprises a strip-folder, supported from beneath thec1othplate of a sewing machine and inclined upwardly toward its deliveryend which is located in front of the feed-do'gs, a lace-guide, supportedby the strip-folder andbetween the same and the cloth-plate, a pivotedlaceconductor, leading a strip of lace-or ed ing to the line of "feedat] substantially right angles and then reversing it into parallelismwith the line of .feed before the lace or edg-' ing entersthelace-guide, and a stripping plate, having an upright edge guidingwall for directing a knit body-fabric into abutting relation; with thelace :or edging, allof the above mentioned features being located inadvance of a combined ruflling and ornamental stitching machine forconcealing the abutting edges of the knit body fabric and lace with acovering-thread of an'attractive color in a figure 8 pattern and forsimultaneously stitching both the fabric and lace to a reinforcingfacing. strip whose raw,

edges are infolded' The knit body fabric is'difl'erentially fed to thestitching point by the ruflling blade to make the stitched articlesmooth and'flat and to prevent it from being drawn or puckered. a

An embodiment of the invention is illustrated in the accompanyingdrawings in which Figure lis a plan view of, the invenvention applied toa machine, parts below, the cloth-plate being exposed by fracturing thelatter. Fig. 2 is a front-elevation of the lat-' tachment .withthe,cloth plate appearing in'sectionQ Fig. 3 is a side elevation of thesame with the cloth-plate appearing in sect on. Fig. tis a sideelevation of the stitch forming and rufliing instrume'ntalities abovethe cloth-plate; Fig. 5 is a cross-section of the work done with thisattachment, and Fig. 6 1s a perspective view of the bracket forsupporting the lace-conductor.

The invention is shown applied to a combined rufillng and ornamentalstitching machine having a ruffling blade 1 secured to an attachment arm2supported in a'bearing of a pivoted hanger 4 and rocked throughalevenarm 5 in a manner full in my pending application erial No.132,521, filed November 21, 1916, and also havinga looping finger 9mounted and oper ated substantially as disclosed in my pend-- ingapplication Serial No. 147,295, filedv vided with a removable section 15cut away to form an opening 16, one side of which a. pears in Fig.4; a Astripping plate 17 having an edge-guiding wall 18,,isadjustably securedover the opening 16. Ashank19 extendin laterally from thestripping plateis slotte M20 and securedby a clamp-screw 21 to an arm 22 which ispivoted by screws 23 to the removable section15 ofthe cloth-plate fromwhich rises a stop-pin 23' for-locating the working position of thestripping plate.

The above mentioned constructionis all located above thecloth-plate,what follows is largely below. p Y

With its upper surface substantially flush with the cloth-plate is alace-guide 24 hav ing an edge-guiding Wall 25, an overhanging lip 26 anda depending and lateral support ing flange which is slotted at 27 forthe screws 28 adjustably securing the guide to a plate 29 projectingfrom one side of a stripfolder 30 to which it is soldered orotherwisesuitably secured; The strip-folder 30 disclosed has the usualedge-folding scrolls or chan-' nels 31 audits rectangularbase-plate 32is movablymounted in a dovetailed slideway 33 provided in a supportingplate 34 screwed.

, toa rod 36 which is adjustably clamped by.

38- depending from the screws 37 in a big e strip-folder is in a planewith and slightly behind'the del-ivery end ofthe lace-"guide 24 which,it will be remembered-,'is flush or nearly so with the porting plate34below the slideway 33 frictionally retains the strip-folder andlaceguide In working position which position" is determined-by thestoprpin' 4O depending from the base-plate 32 to which the stripfolderis fixedly secured.-

A Z bracket 41,- having an lateralarm 42 in which isthreaded-astud-screw 43, pivot ally supports a lace-conductor 44 and a vspring-catch 45 beneath the arm 42 retains the lace-conductor in normalworking position' underneath the cloth-plate during the 1 operation ofthe machine while a friction washer- 46 "at all times steadies theconduc-' tor 44 against'too free movement; "The laceconductorextendspreferably at right angles or'substantially so to the line offeed and itsfree end 47 is bent upwardly and over at an angle intoapproximately parallelis m with thel lineof' feedq Mounted on the lace Tconductor 44 at its r receiving end 0 is a guide-eye 48,-intermediateits ends'is an adjustable tension device 49' ofthe pluralrod type, andi'at itsfree end 47 is an adjustable close'drguizder-loop50; In the bent reversing I from view as well as lend an attractiveapwall 51 of the lace-conductor'isprovided an opening 52 for confiningthe lace durin its reversal and-through a slot 53 communicatingtherewith the lace may be readily introneedles; coveringkthread" '57, ofawfsuitable pleasing color, preferably in a figure 8 pat tern, islaid'to v conceal the. abutting'edges pearancetozthe product. Preferablya facingstrip 58, of woven or other suitable ma-= teriahis secured tothe work with one side underlying the meeting edges of the bodygarmentand lace and with :itsother side secured by the seam 59 of the needle 11to the knit body fabric. The raw edge of the knit body fabric is thussecured against" ravelingwithout foldingit into a bulky -ridge, th emeeting edges of the fabric and, lace are also effectively concealedfrom View,

and the lace and facing strip may be led to the work withoutrequiringattention from the operator during the operation of the machine.
